HYDRAULIC TURBINE.

Patented oct. ac, i914.

Application 4tiled December 24, 1913. Serial No. 808,910.

` To all whom t may concern This invention relates to improvements in'the construction of hydraulic installations and is especially applicableto hydraulic turbine installations of the Francis, direct-coa,

nected, vertical shaft type.

An object of the invention. isto provide a hydraulic installation whichis simple in construction, efiicient in operation, and whichnmay beinstalled at minimum cost.

One of the more speciic objects of theinvention is to provide a simpleand suitable support for the dynamo .electric machine above thehydraulic machine, Without sub# jecting other turbine elements toendanger'-`- ing conditions such as excessive Weights. Another obJect ofthe inventlon 1s to provide suitable struts for directly supporting' thedynamo electric machine of a hydraulic installation from the foundation,these struts being formed as guide vanes which oder the leastobstruction to the fluid passing the struts while entering or leavingthe hydraulic' machine. y

While the invention as disclosed is applied to an installation in whicha direct connected Francis turbine and electric gen- ,cratorvareembodied, it should be understood. that the invention isequallyfapplicable to centrifugal pump installations in which thcdriving motor is located above the pump and is direct connected thereto.y

A 'clear conception of an embodiment of thc invention may be had byreferring to the drawing accompanying and forming a part of this speciiication, in which like reference'characters designate the same orsimilar parts in the various views.

Figure 1 is a top viei'v partly insection, of a Francis type hydraulicturbine installation. l Fig. 2 is a transverse vertical sectionlthroughan installation of the type disclosed in Fig. 1, the sectionbeing taken along the line' lI-l/lf of Fig. 1 looking in the directionoi the arrows. i

.The Francis turbine runner "6 is direct connected with the dynamoelectric machine' or dynamo 9 by. means of the vertical main shaft 7. The runner G is housed in a suitable turbine casing 1'5r which hasthe-main shaft bearing 8 formed in one therewith, and which has itsWeight supported directly upon the foundation through the foundationplate 14e. The discharge end of the. runner 6 Vconnects with thedischarge yfiume 12, which in turn connects with ,the usual tailrace notshown. The mvable guide vanes 5 are mounted in suitable bearingsformedinl the stationary turbine casing 15 and are adapted to cont-rolthe flow of water to the runner 6.l The guide Janes 5' are operable bymeans of the usual guide vane actuating mechanism 11. The stationaryguide vanos 4 are formed in the speed, ring which is secured to thecasing l5 in the usual manner. The turbine inlet casing;l which isdisclosed as a sheet n'ietal spiral casing 1, forms a pressure inletchamber 13 which connects directly with the speed ring 'and turbineinlet opening. The guide vanes 4,'55 are so formed that they direct theWater entering therunner'G from the chambeil 13, toward. the runner atthe proper angle.

The dynamo electric machine or generator 9 is supported upon a suitablelower frame 1() provided with suitable supporting pads at its lowerend.v The struts 3 are arranged in a circular series being formed asdirecting or guide vanes for the Water passing through the turbinecasing, andv are provided at their upper and lowerends With suitablepads. The'pads at the lower ends of the struts 3 coact directly Withthefoundation plate 14;, While the ppads at the upper ends of the strutscoact directly with the pads at the lower end of the frame 10. It willthus be noted that the Weight of the generator 9 is carried directly bythe foundation 2 through the strut-s 3 without subjecting other turbineelements to excessive Weights. Theforma# tion ofA these struts 3 asdirecting or guide Vanves furthermore assists in 'preliminarily icoproperly 'directin the Water admitted to the ioe 13 past the struts 3,stationary vanes Li, and A,

movable guide vanes 5, and through the run# ner 6 to the discharge [lume12. 'lhe power generated by the turbine is controlld by means of theusual. `guide vane actuating mechanism. ll which positions the movableguide vanos While the invention as disclosed shows a sheet metal spiralcasing l, 5 it should be understood that the provision ot u directsupport for the dynamo electric inachine through the struts may heapplied to any other type of casing, such as castl iron, concreteor'other forms generally used. lt o should also be noted that While thestruts 3 are shown in the present ,disclosure as being entirelyindependent of vthe casing l, these struts may le ornied directly in onewith and as a part of the casing l.

it should be understood that it is not de'- sired to be limited to theexact details ct construction shown and described, for obviousmodifications will occur to 'a person sliilledin the art.

`lt is claimed and desired to secure by Letters Patent,-
